Tennis shot from pro: European worker (8)
I believe the answer is:
forehand
'tennis shot' is the definition.
(I know that forehand is a type of return)
'pro european worker' is the wordplay.
'pro' becomes 'for' (I've seen this in another clue).
'european' becomes 'e' (abbreviation e.g. EU).
'worker' becomes 'hand' (hand is a kind of worker).
'for'+'e'+'hand'='FOREHAND'
'from' acts as a link.
(Other definitions for forehand that I've seen before include "Style of tennis stroke" , "shot" , "Court action" .)
